UI announces 2021–22 academic calendar UI announces 2021–22 academic calendar By: Office of Strategic Communication | 2021.04.01 | 08:08 am The University of Iowa has confirmed the dates of its 2021–22 academic calendar with no changes made to the start or end dates for fall 2021, spring 2022, or summer 2022. The calendar also includes an optional four-week winter session beginning Dec. 20 and a weeklong spring break in March 2022. About the winter session The four-week winter session was piloted in December 2020 and January 2021 to allow for select, high-priority courses to be taught. The three-credit-hour classes helped students catch up on a class they might have missed, get a head start on the upcoming semester, work on their career skills, or stay on track for graduation. Most of the courses were offered in a condensed, online format.
